Cater-pillar HEUI Fuel Injectors Suppliers

The Caterpillar HEUI (Hydraulic Electronic Unit Injector) series adopts a proprietary medium-pressure common rail hydraulic drive architecture, specifically developed for high-load applications in construction machinery, heavy-duty trucks, and marine engines. Uniquely utilizing engine oil as the hydraulic medium, the system achieves injection pressures up to 1,600 bar through precision amplification technology—eliminating the traditional mechanical system’s dependence on engine speed and load.

With three core advantages—hydraulic pressure innovation, dual-circuit reliability, and remanufacturing cost efficiency—the HEUI series stands out in extreme operating conditions. It provides critical power delivery for heavy-duty equipment and off-road machinery where conventional fuel systems fall short.
